[PATCH] Use memmove instead of strcpy

[Bernhard M. Wiedemann]

In https://bugzilla.opensuse.org/show_bug.cgi?id=1100488
we found that depending on the build machine, bash-4.4's bash.html would 
contain the string Bahh instead of Bash

strcpy can cause corruption when working on overlapping strings
so we use memmove instead that handles this case correctly
